  • first injection: at elected date,

  • second injection: at least 1 month later,

  • third injection: at least 2 months after second.

Persons at high risk should receive pre-exposure hepatitis B immunisation. These include:

  • Health care and public safety workers who perform works involving contacts with blood or body-fluids;

  • Injecting drug users;

  • Sexually active persons, either homosexual, heterosexual or bisexual;

  • Haemodialysis patients or patients with blood disorders who receive blood products;

  • Household contacts and sexual partners of HBV carriers;

  • Infants born to HBsAg-positive mothers;

  • Those had percutaneous or mucous membrane exposures to blood that might contain HBsAg; and

  • International travellers planning to spend more than 6 months in HBV endemic areas.

It is generally well tolerated. Common side effects include local pain over the injection sites, fatigue, muscle pain, fever, nausea, diarrhoea and headache.
